Magnetic Cannon

Operating entirely without batteries, microchips or an internet connection, this play cannon makes for high-speed fun, setting off a chain-reaction collision powered only by the attractive force of four integral rare-earth magnets.

Known as a magnetic accelerator, the wooden launcher holds eight steel ball bearings, which cling to the powerful magnets within the launcher’s central channel. When a ninth ball bearing is released into the end, it collides with the first magnet. This strike transfers kinetic energy through the magnet and into the next ball bearing, triggering a series of impacts that continue until the last ball shoots from the end of the launcher toward plastic target barrels.

The set includes one magnetic launcher, ten chrome-plated steel ball bearings (including one spare), six target barrels, a small stick used to reset the ball-bearings in the start position, and instructions. Age 10+. An enjoyable way to pass the time on a rainy day at home or at the cottage.
